The following chart shows just how much wrong bettors
will be permitted to wager as single odds on any point
based on a don't pass bet of $10:
4 or 10 $ 20 laid at 2-1
5 or 9 $15 laid at 3-2
6 or 8 $12 laid at 6-5

In
all cases the don't pass bettors are laying odds,
not taking them, and their winner's payoff will be
less than their free odds bet.

Sometimes, at a single odds table, players will be
permitted to lay more than the original bet as free
odds. For example, if they are wagering $5 on the
don't pass line, they'll be allowed to bet $9 at 3-2
against the 5 and 9 as a point rather than just $6
at 6-4.

When double odds are allowed, players can bet up to
double the payoff on their original bet. If the point
is 4 and the wrong bettors have put down $10 on the
don't pass line, they can now wager $40, laying 2-1
odds on the 4 since the payoff, should they win, will
only be $20 on the odds bet. Where double odds are
allowed, $10 bettors, betting wrong, can wager the
following:

Although
you can have a very strong hand before the middle
card is turned, the middle card affects four of the
eight possible three-card combinations. It often turns
a trailer into a winner. Because there have already
been four betting rounds before the middle card gets
turned, huge pots often swing and missed draws often
curse. Someone holding 7V-9V would have his heart(s)
broken by that ace of spades: His open-ended straight
flush draw, a likely winner with any heart, six, or
jack (14 outs: one of the hearts, the Kr, isn't available),
is now worthless.

Another popular variation is called Elevator. Two
vertical columns of five cards each are dealt face
down and they are separated by a single face down
card which can be slid up or down "the elevator"
to be used to form any of five different rows. See
the following figure.]
